Refer to the engine oil filler cap for the preferred engine oil viscosity grade for each vehicle. SAE viscosity grades are used to specify the correct viscosity oil for an engine. Use only Multi-Viscosity oils. These are specified with a dual SAE viscosity grade which indicates the cold (5W) to hot (20) temperature performance range of the oil.
